|title=Proteomic profiling of follicle fluids after superstimulation in one-month-old lambs.
|pubmed-url=https://pubmed.ncbi.nlm.nih.gov/29080277
|abstract=Follicular fluid (FF) accumulates in the antrum of the ovarian follicle. In addition, FF provides the microenvironment for oocyte development, oocyte maturation and competence, which are acquired during follicular development. Superstimulatory treatment of 1-month-old lambs can achieve synchronous development of numerous growing follicles. However, these growing follicles are unable to completely mature and ovulate. Furthermore, the oocytes exhibit lower competence compared with those of ewes. In this study, we utilized an isobaric tag for relative and absolute quantification (iTRAQ)-based proteomics analysis and compare protein composition between pre-pubertal and adult superstimulated follicle FF in sheep. In total, 243 differentially expressed proteins were identified, including 155 downregulated and 88 upregulated between lamb and ewe. Gene ontology (GO) and KEGG pathway analysis indicated that the differentially expressed proteins are involved in signal transduction, anatomical structure development, stress response, metabolic pathways, and the complement and coagulation cascades. Many of the proteins known to affect follicle development were observed in lower abundance in FF of lamb (e.g. [[ADAMTS9]], [[CD14]], [[CTNNB1]], [[FST]], [[GCLC]], [[HSPG2]], [[IGFBP2]], [[IGFBP6]], [[INHBA]], [[PRL]], [[PAPPA]], [[POSTN]], [[PRDX1]], [[SERPINA1]], [[SOD3]], [[STC1]], [[VEGFC]], etc.). However, a higher abundance was observed for proteasome proteins. Inadequate amounts of these proteins in FF may be lead to the unique characteristics of follicular development in lamb. These differentially expressed proteins illuminate the age-dependent changes in protein expression in the follicle microenvironment.

|title=The [[ADAMTS9]] gene is associated with cognitive aging in the elderly in a Taiwanese population.
|pubmed-url=https://pubmed.ncbi.nlm.nih.gov/28225792
|abstract=Evidence indicates that the pathophysiologic mechanisms associated with insulin resistance may contribute to cognitive aging and Alzheimer's diseases. In this study, we hypothesize that single nucleotide polymorphisms (SNPs) within insulin resistance-associated genes, such as the ADAM metallopeptidase with thrombospondin type 1 motif 9 ([[ADAMTS9]]), glucokinase regulator ([[GCKR]]), and peroxisome proliferator activated receptor gamma ([[PPARG]]) genes, may be linked with cognitive aging independently and/or through complex interactions in an older Taiwanese population. A total of 547 Taiwanese subjects aged over 60 years from the Taiwan Biobank were analyzed. Mini-Mental State Examinations (MMSE) were administered to all subjects, and MMSE scores were used to measure cognitive functions. Our data showed that four SNPs (rs73832338, rs9985304, rs4317088, and rs9831846) in the [[ADAMTS9]] gene were significantly associated with cognitive aging among the subjects (P = 1.5 x 10-6 ~ 0.0002). This association remained significant after performing Bonferroni correction. Additionally, we found that interactions between the [[ADAMTS9]] rs9985304 and [[ADAMTS9]] rs76346246 SNPs influenced cognitive aging (P < 0.001). However, variants in the [[GCKR]] and [[PPARG]] genes had no association with cognitive aging in our study. Our study indicates that the [[ADAMTS9]] gene may contribute to susceptibility to cognitive aging independently as well as through SNP-SNP interactions.

|title=Adaptive sequence convergence of the tumor suppressor [[ADAMTS9]] between small-bodied mammals displaying exceptional longevity.
|pubmed-url=https://pubmed.ncbi.nlm.nih.gov/28244876
|abstract=Maximum lifespan varies by two orders of magnitude across mammals. How such divergent lifespans have evolved remains an open question, with ramifications that may potentially lead to therapies for age-related diseases in humans. Several species of microbats as well as the naked mole-rat live much longer than expected given their small sizes, show reduced susceptibility to neoplasia, and largely remain healthy and reproductively capable throughout the majority of their extended lifespans. The convergent evolution of extreme longevity in these two groups allows for the opportunity to identify potentially important aging related genes that have undergone adaptive sequence convergence in these long-lived, yet small-bodied species. Here, we have tested 4,628 genes for evidence of convergence between the microbats and naked mole-rat. We find a strong signal of adaptive sequence convergence in the gene A disintegrin-like and metalloprotease with thrombospondin type 1 motifs 9 ([[ADAMTS9]]). We also provide evidence that the shared substitutions were driven by selection. Intriguingly, [[ADAMTS9]] is a known inhibitor of the mTor pathway and has been implicated in several aging related processes.

|title=Loss of C. elegans GON-1, an [[ADAMTS9]] Homolog, Decreases Secretion Resulting in Altered Lifespan and Dauer Formation.
|pubmed-url=https://pubmed.ncbi.nlm.nih.gov/26218657
|abstract=[[ADAMTS9]] is a metalloprotease that cleaves components of the extracellular matrix and is also implicated in transport from the endoplasmic reticulum (ER) to the Golgi. It has been reported that an [[ADAMTS9]] gene variant is associated with type 2 diabetes. The underlying pathology of type 2 diabetes is insulin resistance and beta-cell dysfunction. However, the molecular mechanisms underlying [[ADAMTS9]] function in beta cells and peripheral tissues are unknown. We show that loss of C. elegans GON-1, an [[ADAMTS9]] homolog, alters lifespan and dauer formation. GON-1 loss impairs secretion of proteins such as insulin orthologs and TGF-beta, and additionally impacts insulin/IGF-1 signaling in peripheral tissues. The function of the GON domain, but not the protease domain, is essential for normal lifespan and dauer formation in these scenarios. We conclude that the GON domain is critical for [[ADAMTS9]]/GON-1 function across species, which should help the understanding of type 2 diabetes in humans.

|title=[[ADAMTS9]] is a cell-autonomously acting, anti-angiogenic metalloprotease expressed by microvascular endothelial cells.
|pubmed-url=https://pubmed.ncbi.nlm.nih.gov/20093484
|abstract=The metalloprotease [[ADAMTS9]] participates in melanoblast development and is a tumor suppressor in esophageal and nasopharyngeal cancer. [[ADAMTS9]] null mice die before gastrulation, but, [[ADAMTS9]] /- mice were initially thought to be normal. However, when congenic with the C57Bl/6 strain, 80% of [[ADAMTS9]] /- mice developed spontaneous corneal neovascularization. beta-Galactosidase staining enabled by a lacZ cassette targeted to the [[ADAMTS9]] locus showed that capillary endothelial cells (ECs) in embryonic and adult tissues and in capillaries growing into heterotopic tumors expressed [[ADAMTS9]]. Heterotopic B.16-[[F10]] melanomas elicited greater vascular induction in [[ADAMTS9]] /- mice than in wild-type littermates, suggesting a potential inhibitory role in tumor angiogenesis. Treatment of cultured human microvascular ECs with [[ADAMTS9]] small-interfering RNA resulted in enhanced filopodial extension, decreased cell adhesion, increased cell migration, and enhanced formation of tube-like structures on Matrigel. Conversely, overexpression of catalytically active, but not inactive, [[ADAMTS9]] in ECs led to fewer tube-like structures, demonstrating that the proteolytic activity of [[ADAMTS9]] was essential. However, unlike the related metalloprotease [[ADAMTS1]], which exerts anti-angiogenic effects by cleavage of thrombospondins and sequestration of vascular endothelial growth factor165, [[ADAMTS9]] neither cleaved thrombospondins 1 and 2, nor bound vascular endothelial growth factor165. Taken together, these data identify [[ADAMTS9]] as a novel, constitutive, endogenous angiogenesis inhibitor that operates cell-autonomously in ECs via molecular mechanisms that are distinct from those used by [[ADAMTS1]].
